Watermelon ’Rosario H’ is an early and high-yielding F1 hybrid that produces juicy, sweet fruits with a thin rind and deep red flesh. This variety thrives even in cooler northern climates, maturing quickly during shorter summers – perfect for anyone wanting to grow sun-ripened melons at home. The round to slightly oval fruits typically weigh between 3 and 5 kg and offer a delightful balance of sweetness and freshness. ’Rosario H’ has a vigorous yet compact growth habit, making it suitable for both greenhouses and warm outdoor beds. Sow seeds indoors in spring in small pots and transplant once the soil is warm and nights are frost-free. Choose a sunny, sheltered spot with nutrient-rich, well-drained soil. Water regularly but avoid waterlogging. For best flavour, allow the fruits to ripen fully on the plant before harvesting. Watermelon ’Rosario H’ impresses with both its earliness and its exceptional taste – the perfect choice for those who want to enjoy the sweetest harvests of summer straight from their own garden.
